Ordering Information

Type NO. Marking Package Code S6510 S6510 SOP-8 O u t l i n e D i m e n s i o n s u n i t : mm SSeemmiiccoonndduuccttoorr PIN Collection

Pin Number Pin Name Pin Function Description 1 Cs Soft start time capacitor connection pin. The pin charge time to Vref determines The preheating time of lamp.

2 C T

Timing capacitor connection pin. The timing capacitor is charged and discharged To generate the sawtooth waveform that determines the oscillator frequency in the internal oscillator. 3 Rs Soft start resistor connection pin. The soft start resistor value determines the initial soft start frequency for preheating. 4 Ldet Input to the protection circuit. If the pin voltage is lower than Vref, the output oh The output driver1,2 is inhibited. 5 GND Ground of the control Section. 6 OUT2 Gate drive output. A push pull output stage is able to drive the Power MOSFET With peak current of 400mA. 7 OUT1 Gate drive output. A push pull output stage is able to drive the Power MOSFET With peak current of 400mA. 8 Vcc Supply V oltage of output driver and control circuits.
